Answers

Answer 1

Answer:

9 times 2

Step-by-step explanation:

Because 22 times 9 is 198 and 20 times 9 is 180 and is you want 198 it will have to be 9 times 2 which is 18 and 180 plus 18 is 198 so yeah.

Answer 2

Answer:

2

Step-by-step explanation:

9*20 + 9*2 would be the equvalent of 9*22

Lee can type 1 1/3 pages every 15 minutes. How many hours does it take him to type 10 2/3 pages? Complete the rate table to solve the proportion.

pages---> 4/3=32/3
hours---> 1/4 = x

Lee can type 10 2/3 pages in _________ hours.
a. 1 3/4
b. 2
c. 2 1/4
d. 2 1/2

Answers

Answer:

First, we know that:

1 1/3 = 4/3

10 2/3 = 32/3

15 minutes = 0.25 hours

Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.

From the information, we can tell that:

Lee can type:

4/3 pages in 0.25 hours

32/4 pages in x hours

So x should be:

x = (32/4 . 0.25)/4/3 = 2 (hours)

So it takes Lee 2 hours ro type 10 2/3 pages

-4(-2x + 5) + 2x + 3 =-11

Answers

Answer:

x = 3/5

Step-by-step explanation:

-4(-2x + 5) + 2x + 3 =-11

Distribute

8x-20 +2x+3 = -11

Combine like terms

10x-17 = -11

Add 17 to each side

10x-17+17 = -11+17

10x =6

Divide by 10

10x/10 = 6/10

x = 3/5

what is the area of a semi circle when the diameter is 6

Answers

Answer: 14.13

Step-by-step explanation:

Your answer is 14.13

First, the formula for area of a semi circle is 3.14 x r^2 and divide by two.

To find the radius, we need to divide the diameter by two, which is 3.

So like

3.14 x 3^2/2

3.14 x 9/2

28.26/2

A=14.13

Answer:

14.13

Step-by-step explanation:

normal circle area equation = r^2*3.14

6/2=3

3*3*3.14

= 28.26

it's a semicircle so /2

=14.13

The graph will show the height of the red car as the time increases. Predict what this graph will look like before pressing start to run the ferris wheel.
How long does it take for the person riding the ferris wheel to make a complete revolution?
One revolution is ____

0 seconds
30 seconds
60 seconds
or
80 seconds

Answers

the correct answer is 60 seconds

As per the graph, the time it takes for the person riding the ferris wheel to make a complete revolution is typically 60 seconds.

When the ferris wheel starts, the height of the red car will initially increase as it ascends from the ground level. As the ferris wheel continues to turn, the red car will reach its maximum height, usually at the topmost position of the ferris wheel, and then descend back to the ground level. This motion will repeat as the ferris wheel continues to rotate.

Now, let's determine how long it takes for the person riding the ferris wheel to make a complete revolution. One revolution corresponds to the time it takes for the ferris wheel to complete one full cycle of motion, going from its initial position, through its highest point, and back to its initial position. This time can be calculated by finding the time period of the sinusoidal function representing the height of the red car.

To find the time period, we need to know the duration for one complete cycle of the sine wave, which is the time it takes for the ferris wheel to complete one revolution. The time period can be derived from the angular speed of the ferris wheel. If we know the angular speed (usually given in rotations per minute or radians per second), we can calculate the time it takes for one revolution.

Determine if the lines are parallel, perpendicular, neither or the same line: y = -2x + 1 and -2x + 4y = 5.

Answers

Answer: These lines are perpendicular

Step-by-step explanation:

Let's use slope intercept form, y=mx+b (m=slope, b=y intercept)

Parallel lines have the same slope, or m

y=3x+7 and y=3x+32 are parallel because they have the same m

Perpendicular lines have an opposite reciprocal slope

y=2x+13 and y= -1/2+2 are perpendicular because they are reciprocals

y=-2x+1 is already in slope intercept form. Let's change the other problem

-2x+4y=5isolate the y, 4y=2x+5make y by itself, y=2/4x+5/4 or y=1/2x+5/4

Here are the two problems: y=-2x+1 and y=1/2x+5/4

Look closer. These lines are actually perpendicular.

Take the second problem's slope, 1/2. Make it a negative reciprocal, which means -2/1 or -2. These lines are perpendicular.

They are perpendicular
